Ron, I recently finished making a Leg-O-Mutton case. I used both the 3M brand plus the cheaper equivalent spray adhesive from K-Mart - couldn't tell the difference in application. I allowed a couple of minutes drying time after I sprayed the interior of the case and the billiard cloth before attaching. You may wish to lay some waxed paper over the adjacent case areas to prevent overspray from the adhesive.
